CAUTION

Installation and Piping

• Non-explosion-proof transmitter must not be used in a place with explosive gases to prevent

serious accidents such as explosion, fire, etc.

• The transmitter is heavy. Be careful when handling it.

• The transmitter should be installed in a place that meets the operating conditions shown in DS

sheet or this instruction manual.

• Install the transmitter according to the instruction manual. Improper installation may lead to the

cause of fall, trouble or incorrect operation.

•When installing, make sure that the transmitter interior is free from cable chips and other foreign

objects to prevent fire, trouble, or incorrect operation.

•When power is ON, do not change the position of the field indicator in an explosion-proof area.

•When power is ON, do not change the position of the transmission unit in an explosion-proof area.

•When power is ON, do not change the angle of the indicator.

•Main valve used for piping should be selected with the maximum pressure of the process taken

into account (piping parts such as main valve, etc. should be furnished by user). If the main valve

and other parts do not meet the rating, it may result in leakage of gas or liquid which could lead to

hazard.

• Pressure pipes to be used must meet the temperature/pressure rating.

• The cautionary descriptions listed here contain important information about safety, so they should be

observed without fail. Those safety precautions are classified into ranks “DANGER” and “CAUTION”.

Wrong handling may cause a dangerous situation, in which there is a

risk of death or heavy injury.

Wrong handling may invite a dangerous situation, in which there is a

possibility of medium-level trouble or slight injury or only physical

damage is predictable.

On items listed under “

CAUTION

”, they may also lead to serious accidents depending on circum-

stances, and must be fully observed.

• The signs of prohibition and indication are explained in the following.

General items which pertain to prohibition (DO NOT)

General items which pertain to user’s action

CAUTION ON SAFETY

First of all, read this “Caution on Safety” to ensure correct operation of the

transmitter.

DANGER

CAUTION

DANGER

Wiring

• On explosion-proof type transmitter, its wiring work must be performed according to the required

laws and regulations. Incorrect wiring may cause explosion, fire or other serious accidents.

• Before making wiring work, be sure to turn OFF the main power to prevent electric shocks.

• Use wiring materials of correct rating to prevent fire accidents.

• Connect a power source of correct rating to prevent fire accidents.

• The transmitter should be grounded as specified to prevent electric shocks or incorrect operation.

• After installing the transmitter, firmly close the covers of the transmission unit and terminal box.

If not, rain water enter the transmitter which may result in trouble or incorrect operation.

Adjustment of Smart Type

•When using a flame-proof transmitter, do not connect HHC to the transmitter terminals and junc-

tion terminals.

Replacement of Maintenance Parts

•When removing an explosion-proof transmitter, turn OFF the main power, then disconnect the

piping and wiring. Do not remove it when the power is ON to prevent serious accident such as

explosion, fire, etc.

iv

Storage for a long period

Store the transmitter in a dry room at normal temperature and humidity.

Keep protection caps in place at the conduit connection and process connection.

For installation, select an appropriate place

Site at location with minimal vibration, dust and corrosive gas

At a place allowing an adequate space for checkup

Site at location large enough to allow maintenance and checking.

Mounting angle

Mount to a pipe horizontally or vertically.

Attention to overload

Do not apply a pressure outside the specified range.

Other

Besides the above, be sure to observe the cautions given in this manual.

The instrument nameplate as shown below is attached at the transmission unit of this transmitter. Before

use, make sure the contents of the nameplate agree exactly with your specifications.

OUTLINE

The FCX-CII series transmitter detects the differential pressure or pressure of various

fluids, converts it into a current signal of 4 to 20 mA DC and transmits it.

All the adjustment functions are incorporated in the transmission unit for making

adjustments easily and exactly.

Transmitter settings (such as range and damping time constant, etc.) can be changed from

an HHC (Hand Held Communicator).

Principle

The operating principle of the FCX-CII series transmitter is shown in the block

diagram below.

The input pressure is changed into an electrostatic capacitance in the detecting unit.

The change proportional to the pressure undergoes conditioning and amplification in

the transmission unit, and is then output as a current of 4 to 20mA DC.

(2) Check the signal wiring according to the “Terminal block connection diagram” shown in 4.1

(Page 16).

(3) Vent gas from the transmitter.

Preparation procedure

(4) Perform zero point adjustment.

When the plant requires chemical cleaning at the start of operation, be sure to

close the valve of the transmitter to prevent entry of cleaning liquid into the

pressure receiving unit.

Important

3.1 Preparation for operation

Before operating the transmitter, be sure to perform the following checks and procedures. Note

that adjustment is required in a non-hazardous area for zero point check of intrinsically safe

explosionproof and flameproof transmitters, do not open terminal cover and do not use HHC.

Use the transmitter indicator and the external adjustment screw.

(1) Check for liquid or gas leakagefrom the process

connection, etc. by applying soapy water or the

like.

5

1. After adjustment of the transmitter, it should be kept energized for about 10

seconds to write the adjustment result into memory.

2. Use a blade-edge screwdriver for adjusting the zero/span adjustment screw.

Important

Decrease

Increase

When all the checks and preparatory operations are finished, tighten the cover securely. (Tighten-

ing torque 20 N•m {2 kgf•m} <14ft-lb>)

Zero point check

Turn on the power to the transmitter.

Check the output signal of the transmitter by connecting a DC ammeter across CK+ and CK– of

the terminal block.

After ten minutes or longer, adjust the transmitter output current to 4 mA (zero adjustment). (See

below.)

(1) Zero adjustment

Zero point of the transmitter is adjustable by the zero screw on the electronics housing with

the zero adjustment screw.

• If the transmitter is locked (see section

“Operating procedure”, Lock of adjustment

function), it is not possible to adjust with the

external adjustment screw.

• When a digital indicator is attached to the

transmitter, make sure that the LCD lamp

“ZERO” is ON.

(2) Adjustment by HHC

Refer “zero adjustment” explained in section 7.1.

3.2 Operation

(1) Operation of pressure transmitter

Open the valve slowly to apply a pressure. When a pressure is applied, the transmitter is set

in the operating status.

(2) Operation of differential pressure transmitter

Set the operating status by manipulating the manifold valve.

Make sure the equalizing valve is open.

Open the stop valve on the high pressure side slowly.

Close the equalizing valve.

Before a long shutdown, discharge the process fluid and drain completely from

the transmitter.

This is to protect the transmitter from freezing, corrosion, etc.

ADJUSTMENT OF SMART TYPE

To operate the FCX-CII series transmitter, the HHC is used for each adjustment.

4.1 Adjustment with HHC

Startup and usage of the Hand Held Communicator (HHC) are detailed in the instruction manual

for HHC. Please refer to this manual before commencing adjustment.

The HHC can be connected to the transmitter, junction terminal or the terminals in the instrument

room.

Important

In case of the actual scale specification with a digital indicator

provided, if the range is changed, indicator display does not match.

So, setting is required again in response to the display in the digital

indicator (G: XMTR DISPLAY). In case of the actual scale

specification with an analog indicator provided, if the range is

changed, indicator display does not match. So, replacement of the

analog indicator is required.
